Bitcoin (BTC) rose 5% during US trading on Sep 3, 2026, reclaiming $80,000 and reaching $81,000. The gain came as the Japanese yen strengthened and the US dollar weakened.
USD/JPY fell to 155.4, down from 158.5 a day earlier, amid a suspected Bank of Japan currency intervention. The US Dollar Index (DXY) dropped to 99. A weaker dollar has historically coincided with higher Bitcoin prices.
Polymarket odds of a Bank of Japan rate hold fell from 12% to 1%, with markets pricing a 98% probability of a 25-basis-point hike on Sep 18. Some observers flagged renewed carry-trade unwind risk.
Analysts remain split on how much of the move the suspected yen intervention explains.
